Presence Sensor
Item no.: presence-sensor

A presence sensor is one of the most important sensors in any type of automation project. With reliable detection of presence and motion, it forms the basis for the automation of important functions such as lighting (including maintaining constant light levels), burglar alarm, music, heating, ventilation or cooling, and much more. This is how you can easily solve seemingly complex tasks:

  • Detect movement and presence through infrared and acoustic sensors
  • High detection field with a detection angle of 360° horizontal and 110° vertical (giving you an 8m detection field at a ceiling height of 3m).
  • Integrated brightness sensor (measuring range 0 ... 83000lx)
  • Individually adjustable acoustic sensor threshold value for presence detection.
  • Individually adjustable acoustic sensor threshold value for the burglar alarm.
  • Simple limitation of the detection range using a sticker for the Fresnel lens

Unique multi-sensor capability: Infrared, Acoustic, and Brightness

Unique multi-sensor capability: Infrared, Acoustic, and Brightness

A traditional motion sensor does not detect when a person is sitting e.g. at a desk or in front of the TV set and is not moving. Installation factors might also affect the effectiveness of a motion sensor, such as it being hindered when a door is ajar. This is why we developed the Loxone Presence Sensor – to reliably detect presence more in more installation environments. With built-in multi-sensor technology, you can reduce hardware costs in non-traditionally shaped rooms that would have required multiple motion sensors.


High detection field with a detection angle of 360° horizontal and 110° vertical (giving you an 8m detection field at a ceiling height of 3m). The sensitivity can be set to one of 4 different values.


Once presence has been detected by motion, then the presence factor can be extended by sound detected by the acoustic sensor. The threshold value of the acoustic detection can be set via Loxone Config.


A high-quality brightness sensor (measuring 0 … 83000lx) is perfectly suited for the implementation of brightness-dependent functions such as constant light levels and Daylight Responsive Lighting.

Versatile Acoustic Sensor

With the built-in acoustic sensor, the Presence Sensor Tree offers an even wider range of possible applications.

Time-Out Extension

With motion initially being detected, the audio sensor within the Presence Sensor can then extend the time out automatically – even if no motion is detected.


If neither motion nor audio has been detected within the preset period, then – for up to 10 seconds after this period – the Presence Sensor will still listen out for any audio to extend the time-out (for example, a clap).


If a certain noise level is exceeded (adjustable in Loxone Config), the alarm output of the Presence Sensor is activated. With this, you can realise different functions such as triggering a notification or an alarm.

How the acoustic
detection works

The Presence Sensor is equipped with an acoustic sensor that detects noises and measures the volume level. The volume level is then transmitted to the Miniserver.


Presence Detection for Ambient Assisted Living

Especially when older people live alone at home, it is important for relatives to know that everything is in order. This can be achieved with presence detection as a form of unobtrusive monitoring. For example, an alarm could be triggered based on fall detection, changes in behaviour, or other such emergency situations.

Installation and Configuration

With the fibre-reinforced mounting bracket, the Presence Sensor Tree can be easily and securely mounted on either the ceiling or the wall. Plus, coupled with the know-how of a Loxone Partner, Loxone Tree offers unparalleled ease of install and commissioning through Loxone Config.

loxone tree

The award-winning Loxone Tree Technology was designed with a clear goal in mind: reduce the cable and effort required for all the peripheral devices in a home or building automation installation. Thanks to a free-form wiring topology and intuitive configuration software, Loxone Partners are able to commission Loxone Tree devices in record time
